BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an adjustable pull-out frame structure, and more particularly, to an adjustable pull-out frame structure which is applied fixedly inside a closet or locker, to which a frame of the adjustable pull-out frame structure is adjustable according to a size of the cabinet body, thereby making it universally available for any cabinet body.

2. Description of the Prior Art

It is common for every household or company to have a closet, a locker or other kinds of cabinet for placing clothes or other stuff inside it. Therefore, people purchase custom-made cabinets or factory-designed cabinets. No matter these cabinets are custom-made or factory-designed, they are manufactured according to personal preference or factory requirement. Though these finished cabinets show beautiful appearances, it is hard to change the sizes of the compartments or the partitions of the cabinets. People will have these cabinets re-designed and modified, or have to use the compartments of the cabinets as before. Besides, sometimes it is not convenient for people to get their clothes from closets or dishes/plates from cupboards if those closets or cupboards are full with clothes or dishes/plates respectively. For example, when a person wants to take out his/her clothes, it is often that he/she will find the clothes tangled with other clothes, making it inconvenient to use.

Therefore, the above-mentioned conventional implementations for cabinet body present several shortcomings to be overcome.

In view of the above-described deficiencies of conventional cabinet body, after years of constant effort in research, the inventor of this invention has consequently developed and proposed an adjustable pull-out frame structure in the present invention.

SUMMARY OF THE INVENTION

The present invention is to provide an adjustable pull-out frame structure, whose length/size is adjusted by using a retractable rack to fit in a length/size of the frame of the cabinet body to be applicable in any cabinet body.

Another, the present invention is to provide an adjustable pull-out frame structure, which provides a sliding rack having a sliding pull rod set which can slide in or out of the cabinet body. When the frame is installed inside the cabinet body, it can be pulled out by a user, besides, a number of anti-slip strips are arranged on a joining rack, and therefore it is convenient for users to get their clothes or stuff.

The present invention discloses an adjustable pull-out frame structure, which comprises sliding racks, joining racks, retractable racks, retaining blocks, a bolt and a locking element; wherein two sliding racks are installed face-to-face to each other, each sliding rack having a sliding pull rod set placed behind the sliding rack, and two mounts being installed on each one of the sliding pull rod sets, each sliding rack having each of its both ends connected to a joining rack respectively, and each joining rack having a retaining rail installed on an upper side thereon, then each joining rack having its one end placed in contact with a retractable rack, each one of the two retractable racks having a hole implemented on an upper side thereof, and the hole being installed with respect to the retaining rail on the joining rack, and a guiding hole being installed in the middle of each retractable rack, then a retaining block being inserted through the retaining rail and hooked up in the hole, finally, each joining rack on each side of one sliding rack being connected to each retractable rack through the insertion of a bolt, while each joining rack on the other sliding rack being locked to the sliding rack by a locking element, in this way the two sliding racks, joining racks and retractable racks being connected with each other to form the adjustable pull-out frame structure. The adjustable pull-out frame structure can have its length/size adjusted by using a retractable rack to fit in a length/size of the frame of the cabinet body to be applicable in any cabinet body.

These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying Drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer from FIG. 1 to FIG. 6 for the adjustable pull-out frame structure disclosed in the present invention, which mainly comprises two sliding racks 1, a first joining rack 2, a second joining rack 3, two retractable racks 4, at least one retaining block 5, at least one bolt 6 and at least one locking element 7.

The sliding racks 1 are installed face-to-face to each other, each sliding rack 1 having a sliding pull rod set 11 placed behind the sliding rack 1, and two mounts 111 installed on each one of the sliding pull rod sets 11. One of the sliding racks 1 is fixed to a cabinet body by the mounts 111.

The first joining rack 2 has a retaining rail 21 installed on an upper side thereon, and a socket 22 formed on a side of the first joining rack 2. The socket 22 of the first joining rack 2 is placed to be in contact with one end of the sliding rack 1, while the other end of the first joining rack 2 is placed in contact with a retractable rack 4. The first joining rack 2 can have a plurality of anti-slip strips 23 placed thereon for a user to pull out the frame by means of anti-slip strips 23.

The second joining rack 3 has a retaining rail 31 installed on an upper side thereon, and a socket 32 formed on a side thereon. The socket 32 of the second joining rack 3 is placed to be in contact with one end of sliding rack 1, while the other end of the second joining rack 3 is placed in contact with a retractable rack 4.

Each retractable rack 4 has a hole 41 implemented on an upper side thereof, and each hole 41 is installed with respect to the retaining rail 21 of the first joining rack 2 and the retaining rail 31 of the second joining rack 3 respectively, and a guiding hole 42 is installed in the middle of each retractable rack 4. Each retractable rack has its two ends connected to the sockets 22, 32 of the first and the second joining rack 2,3 respectively. The guiding hole 42 is for the insertion of a bolt 6.

The retaining block 5 has a buckling element 51 extending from the bottom thereof. Each retaining block 5 is inserted into the retaining rail 21 of the first joining rack 2 or the retaining rail 31 of the second joining rack 3 respectively and is held inside the hole 41 of the retractable rack 4 to control an extension length of the retractable rack 4.

A front end of the bolt 6 is formed slightly of an elliptic shape. The bolt 6 is inserted through the first joining rack 2 and has a front end of the bolt 6 going through the guiding hole 42 of the retractable rack 4. The front end of the bolt 6 is formed slightly of an elliptic shape and other flange-like shapes, thereby fitting the bolt 6 closely with the guiding hole 41 of the retractable rack 4;

The locking element 7 locks two sliding racks 1 with the second joining rack 3. The locking element can be a screw or other fastening elements;

The adjustable pull-out frame structure disclosed in the present invention can be used in any type of cabinet bodies 8 for household or company use. Please refer to FIGS. 3A, 3B and 3C, since the frame structure can have its length adjusted by using a retractable rack to fit in a length the frame of the cabinet body, it is applicable in any cabinet body 8. Besides, the present invention provides a sliding rack 1 having a sliding pull rod set 11 which can slide in or out of the cabinet body; it is convenient for users to get their clothes or stuff. Furthermore, the frame structure contains a hollow portion in the middle for accommodating bodies 9 of different capabilities to hook up with the frame (as shown in FIG. 4 to FIG. 6). Therefore the present invention can provide multiple functions in one frame structure to facilitate the use of the cabinet body.
